A container may have a base, a sidewall connected to the base, a bell connected to the sidewall, and a finish connected to the bell. The base may have strap ribs to resist deformation of the base. The sidewall may have recessed columns to resist bending, leaning, crumbling, and/or stretching. The strap ribs and recessed columns may vertically line up along a central axis of the container to communicate forces on the container vertically along the container to continuously resist.

Please delete the current abstract and insert the following new abstract: A container includes a flat foot base having a gate centered on a central axis of the container and a sidewall connected to the base and defining a portion of an interior of the container. A plurality of strap ribs are positioned in the base, each one of which extends radially outward toward the sidewall. A plurality of recessed columns are positioned in the sidewall and formed from varying depth sidewall ribs extending along a periphery of the sidewall. Each varying depth rib includes shallow sections and deep sections, the shallow sections having a rib depth less than a rib depth of the deep sections. The shallow sections of the varying depth ribs are aligned to form the recessed columns. At least one strap rib is aligned with at least one recessed column.

A stretched and foamed plastic formed body forming, in at least a portion thereof, a foamed region which incorporates foamed cells therein, wherein the foamed cells have a flat shape with a maximum thickness of not more than 30 μm and an average aspect ratio of not less than 4 as viewed in cross section of the formed body perpendicular to a direction in which the formed body is stretched to a maximum degree, and a non-foamed plastic skin layer having no foamed cell distributed therein is formed on the outer surface of the foamed region. The formed body is, further, blended with a non-lustrous pigment as the coloring agent, which is different from a lustrous pigment such as flaky pigment, and exhibits a metal color over the foamed region thereof. The foamed formed body exhibiting a metal color and, specifically, a gold color or a silver color is thus provided without using any expensive lustrous pigment such as metal powder pigment or flaky pigment.

A blow molded monolayer article. The article has a hollow body defined by a wall. The wall has one or more regions comprising a first composition and one or more regions formed by a second composition.

Preform (1) made of a plastic material for the manufacturing of a container (2) by blow molding or stretch-blow molding, the preform (1) including a sidewall (20) extending along a main axis (Z), an open neck (4) and a substantially hemispherical closed bottom (21) having a thickness (T) which varies at least locally around the main axis (Z).

Described are a mold and molding process for manufacturing devices and containers that are scalable, modular, and lockable laterally and vertically with other like devices or containers. The mold is formed with a cup mold and top end mold sections specially designed to allow for molding and demolding a container with an undercut. The cup mold includes, on a vertical wall, one or more undercuts. Multiple undercuts may further form tongues with undercuts each of which forms a groove with undercuts on the molded article, and/or one or more grooves with undercuts each of which form a tongue with undercuts in the molded article. Molding and Demolding of the article with undercuts is further enabled by utilizing an improved method of molding said article with an undercut, and demolding said article from the mold once it is molded, by improvements to each stage of the molding process, including the preform stage, the conditioning station stage, the blow stage and the release stage.

To provide a composite preform that can ensure that worsening of the appearance of a surface of a plastic member caused by near-infrared heating prior to blow molding is effectively prevented and that an inner preform is efficiently heated. The composite preform of the present invention includes a preform and a heat-contractive plastic member, the preform including a mouth part; a trunk part linked to the mouth part; and a bottom part linked to the trunk part, and the heat-contractive plastic member being disposed so as to surround the outside of the preform and including at least a colored layer that contains a resin material and a colorant, wherein the heat-contractive plastic member has a near-infrared transmittance of 50% or higher.

A machine for producing a container from a preform having a body and a neck defining an inner cylindrical opening. The machine includes a container forming and filling station where the preform is placed in a mold having a molding cavity and a forming liquid is injected into the preform thereby forming and filling the container with a liquid. Prior to forming of the container, an extension device is attached to the neck of the preform thereby forming an assembly. The extension device includes a connection part for attaching to the preform and an extension part defining an inner opening extending in the continuity of the inner opening of the neck of the preform. The extension device remains attached to the neck of the preform at least during the forming and the filling of the container.

A preform is provided for blow-molding to form a container. The preform includes a finish portion for rotatably engaging a closure to seal pressurized contents within an interior of the container. The finish portion comprises a cylindrical body that begins at an opening to the interior and extends to and includes a tamper evidence ledge. A bevel at a beginning of the opening receives a plug seal of the closure. Multiple mirror polished surfaces beyond the bevel are configured to cooperate with the plug seal to seal the container. Mirror polished transition surfaces are disposed between diameter changes within the finish portion. In some embodiments, wherein the plug seal includes a sidewall profile that mates with the transition surfaces, an interior surface of the preform has a diameter that tightly compresses an end of the plug seal to contain pressurized contents within the container.

A preform configured to form a container by stretch blow molding. The preform includes a finish portion and a tip portion. The finish portion is at a first end of the preform and is a container finish of the container. The tip portion is at a second end of the preform opposite to the first end. The tip portion is configured to form a container base and a container heel of the container. An outer surface of the tip portion includes a flat surface, a first radius on a first side of the flat surface, a second radius between the first radius and the flat surface, a third radius extending from the flat surface on a second side of the flat surface, and a fourth radius extending from the third radius towards the second end of the preform through which a longitudinal axis of the preform extends.
